Yang Wenli is a reborn, he has seen several social systems, he found a law, a country cannot achieve equality for all, that is a utopian idea, there is no real society, why? Because people are thoughtful, because of their different positions, inequality naturally arises, such as subordinates and superiors.

In modern society, Europe and the United States call it the middle class, and those minority elites are not counted, because their proportion of the overall national population is too low, and if they form a sharp opposition with other nationals, then a change of dynasty is not far away.

Therefore, in essence, the cornerstone of the country is the vast middle class, and when you change to the Black Armor Army, in addition to the vast number of soldiers of the Black Armor Army, it should be those civilians.

The Black Armor Army has no grudges against those civilians, only kindness and righteousness, and it is a class that can be fought for, and Yang Wenli wants to develop them into a profiteering class.

Therefore, in some aspects, some relatively modern systems have been adopted, such as being responsible for food and clothing for the whole people, and finding ways to solve jobs.

Before their lives are stable and their food and clothing are not solved, they should not mention taxes, except for the tax on acres of land, Changsheng Island is currently free of taxes, no matter what industry they do.

Yang Wenli is different from other reborns, he has more advanced technology, and it is easy to make money, such as high-end bone china, glass mirrors and glass products, sulfur soap, and so on.

But he didn't want to trade them for money, unless he had to exchange them for much-needed supplies.

In his understanding, gold and silver are useless things, no different from ordinary metals, and only productivity is the real wealth.

Everything depends on self-reliance, originally in ancient times, it was also a pure agricultural economy, and the dependence on the outside world was very low, Yang Wenli also wanted to do it more thoroughly, except for the basic materials that he did not have, he would not trade with the outside world.

Note that it is a material rather than a commodity, the former is the basic raw material, the latter is the product, and if you import a certain product, it means that there is a loss of some jobs under your rule.

Yang Wenli wants to develop a completely new system that has never appeared in history to see if it can speed up the development of science and technology and the progress of society.

At present, Yang Wenli's cultivation of the middle class system is still very good, the effect is very good, the majority of ordinary people, the Black Armor Army is sincere support, has a strong sense of ownership, and when talking to people, I will be called the Black Armor Army.

This is mainly due to the significant difference between their status and slaves, the slave black armor army does not care, and depends on the right master, such as Yang Wenli's slave soldiers, etc., the status of ordinary officials is not as high as theirs.

Where there is contrast, there is a sense of superiority, this is the positive meaning of the class system, the civilians under the rule of the Black Armor Army belong to the middle class, and their sense of ownership is naturally higher than that of the civilians under the rule of other forces.

Not only were the common people exempt from all taxes before the middle class, but Yang Wenli also considered that in the future, official appointments, examinations, etc., could only be qualified by commoners.

The life of the vast number of slaves is the responsibility of their masters, but they must also be fed, can be beaten and scolded, and even re-sold, but they are not allowed to save food, because the soldiers of the Black Armor Army are from these slaves at the bottom of society, this is their only way to promotion, other than that, they can't earn a penny, except for the master's reward, so they can't turn over from other ways.

The new system envisaged by Yang Wenli, he ordered the logistics department to be implemented slowly, and everything still depends on the test of time.

He himself was still staying in the workshop, leading Wang Rucheng and his slaves to develop mortar shells, and after the mortar barrel was developed, they could experiment with the appearance of mortar shells.

The mortar shell is a typical spindle, with an interface in the front fifth, which must be wired, where is the junction between the bump fuse head and the projectile body, and at the same time the opening for explosives, steel balls and detonators.

The rear part is gradually retracted, and to the tail is three tail fins, and ordinary mortars have no rifling, relying on a few small tail fins to produce rotary stabilized shells.

In the middle of the tail is the propellant tube, which must cast a cylindrical cavity and place the propellant tube, because the propellant is nitrocellulose, which is very easy to catch fire and explode, and must be transported and stored separately from the safety explosives inside the bomb body, and is loaded only before launching, and the detonator inside the bomb body must be loaded before launch.

The mortar is a smoothbore gun, and the air tightness is not strong, so the outer edge of the bullet body must be cast out of three brass sealing belts, which is the same principle as the cylinder liner piston ring of the engine.

This process is easy in modern society, but in ancient times, it gave Yang Wenli a big problem.

Copper and pig iron are two kinds of substances, and pig iron is still cold, these simple copper hoops are difficult to stabilize, can not pass the ordinary physical and mechanical tests, let alone test firing in the barrel, if you don't do it, it will not be launched successfully, and it will explode in the barrel.

In the end, Yang Wenli had no choice but to put a few slots on the bullet body, so that the problem was finally solved.

After the groove is cared, the copper hoop is equal to the piston ring, and it is difficult to fall off whether it is stable or not.

It is only the suitability of the hydrodynamic properties and the specific gravity of the front and rear of the experimental projectile, so the explosive steel ball does not have to be loaded in the projectile body, but it must be the same weight as the explosive, the steel ball and the collision fuse, otherwise the experiment will lose its meaning.

Therefore, Yang Wenli had to assemble a live bomb, weigh it, and then subtract it from the empty bomb with the launch tube to get the weight, and then fill the bomb body with sand and other substances, instead of real explosives, steel balls, and collision fuses for experiments.

It is very troublesome to engage in scientific research, and it is often a problem that is intertwined, and it is necessary to solve it step by step from scratch.

Time is in Yang Wenli's dedicated scientific research, silently passed, it was the end of March, under the influence of the ocean current, the weather is getting warmer and warmer, the ice and snow began to melt gradually, first of all, the thick snow on the ground is gone, and the ice wall built with more than 10,000 slaves last year is melting inch by inch, and it seems that it is useless.

The ice on the sea surface has become thinner, and it is no longer suitable for walking, and Changsheng Island has finally passed the dangerous period, and there is no need to be afraid of the Jiannu army, which day will suddenly attack the island.

In fact, Jiannugen didn't have time to take care of him, just last month, Huang Taiji killed the envoy with the Chahar Dorot Department, personally broke it, and captured more than 12,000 people.

His excuse is very weak, the envoy he sent is not a peace messenger, but a messenger who specializes in digging the foot of the Chahar wall, Huang Taiji is busy recruiting the tribes that have been subjugated by Chahar, and it is strange that the Dorot Department does not kill people.

But the so-called strong are justified, just like today's US imperialism, they can hit others with just an excuse. The Eight Banners were well-equipped, and the Mongol tribes like Hanako were no match for them at all, and the results of this battle were brilliant, and their own losses were slight, which further enhanced the vigorous fighting spirit of Jiannu and significantly enhanced the confidence of the Mongol tribes to join them.
